Let’s examine the evidence. We’re at the Billboard Music Awards. The Chainsmokers and Halsey are giving an endearing acceptance speech, having just won the Top Collaboration Award for their song “Closer.” It’s the first award of the evening, and a sense of anticipation and potential is in the air.

The speech wraps up. Yet as the camera pans out onto the clapping audience, the light-hearted mood hits a snag. And that snag is Lorde’s arched, skeptical eyebrows and a smirk that stopped a thousand ships.

This is Lorde's Mona Lisa moment. This is a half-smile cloaked in mystery. What opinions does her wry smile mask? Who is the intended recipient of that eyebrow wave?

Twitter decided to read deeply into the smirk, concluding Lorde’s expressive face was a reaction to the Chainsmokers and Halsey’s win. People assumed that Lorde's face meant she isn't a fan of the Chainsmokers.

At first, it might be tempting to agree with Twitter that Lorde, writer of sophisticated and intellectual pop songs, would look down at the Chainsmokers’ exuberant chart-topper "Closer." But before we ignite a rivalry in the music world, let’s put Lorde’s expression into perspective.

After taking a deep dive into Lorde's Instagram, we can safely say that the “smirk” is, in fact, one of the singer's favorite poses. Odds are, Lorde was just smirking because she’s Lorde, and that is her face.

Here's proof. Lorde smirks when she’s at her birthday party with Taylor Swift.
